Which calibration file should I use and where to point the UMIK-1?

We provide two calibration files to be used depending on your application.

- For stereo system (e.g. 2ch dirac live, single speaker measurement), use the 0deg file and point the UMIK-1 at the speakers
- For multichannel system (E.g. 5.1/7.1) or a surround application where multiple speakers are spreadout around the room, use the 90deg file and point the UMIK-1 at the ceiling.

The miniDSP team built long term relationships with the following leading software applications and is proud to showcase them as our recommeded software solutions:

REW: miniDSP worked along with John Mulcahy to develop even greater compatibility for the UMIK-1 inside REW! With the latest beta release of REW (v5.01 and up), the UMIK-1 is automatically recognized by the software and prompted for use when REW is started with the microphone plugged in.


Please follow our application note for more information.

Dirac Live: As a well known reference in the world of room correction with countless high end audio/automotive, we're honored to have Dirac as part of our partners. The UMIK-1 is the recommended microphone by Dirac Research.


Umik-1 on Ipad: Our technical team has been testing the UMIK-1 along with few ipad apps. A plug&play setup for a full featured measurement + SPL meter running from the Ipad. Check out our application section for more info.

Amarra Symphony: Amarra Symphony with IRC is an advanced music file player for the Apple Mac platform. It includes a feature called "Impulse Response Correction" (IRC), that corrects for acoustical errors at the listening position caused by early reflections from the speaker and listening room. It also provides the ability to tailor the response at the listening position using target curves.
